FIELD OF THE INVENTION

The present invention relates generally to a system and method for routing phone calls to provide a positive and personalized service environment. More particularly the present invention relates to a system and method for providing call-back options.

BACKGROUND OF THE INVENTION

It is increasingly common that consumers seek service from business concerns using the telephone. For example, a consumer seeking to place an order, schedule a 20 delivery, file a complaint, or query an account balance may place a call to a centralized number provided by a business concern. It is well known that businesses often provide such numbers as so-called toll-free “800” numbers or the like. Some toll-free sites are so-called “virtual call centers,” where callers interact with a “front-end” interactive voice response unit (IVR or VRU) before their calls are routed to agents at call centers at different geographic locations.

Due to high call volumes and limited system resources calls received at a virtual call center may be queued according to the order in which they are received. A caller sometimes may have to wait on line for an extended period of time before an agent becomes available. There are a number of disadvantages in keeping customers on hold. First of all, such long and boring experiences often result in customer dissatisfaction. Second, running out of time or being impatient, some customers may prematurely end the call, which may result in loss of sales. In addition, keeping a number of phone lines actively connected to a virtual call center for a long time also means more costs for the host business.

A few solutions have been proposed to alleviate these problems. Some solutions attempt to estimate a length of time that a caller may have to wait before a call center gent becomes available. The estimated watt time is typically announced to the caller periodically when the caller is on hold. Another solution goes one step further by not only estimating an estimated wait-time but also offering to call the caller back after She estimated time period expires. However, these solutions only provide limited options for the caller and are not flexible in their implementations.

Other problems and drawbacks also exist.

SUMMARY OF THE INVENTION

In view of the foregoing, it would desirable to provide a solution for managing phone calls at a virtual call center which overcomes the above-described deficiencies and shortcomings.

DETAILED DESCRIPTION OF THE INVENTION

Reference will now be made in detail to the present embodiments of the invention, examples of which are illustrated in the accompanying drawings.

FIG. 2 is a flow chart illustrating an exemplary method for providing call-back options according to an embodiment of the present invention.

In step 200, a phone call may be received from a caller (“customer”). The caller may be calling into a call routing system for a number of reasons. For example, the caller may be an existing custom calling for customer service. Or the caller may be a potential customer calling to take inquiries and/or place orders. The caller may be greeted by an interactive voice response unit (IVR or VRU). The IVR may collect information, from the caller (e.g., using touch-tone activated voice menus and/or voice-recognition technology). According to one embodiment of the invention, at least part of the caller's information may be identified or confirmed via Automatic Number Identification (ANI). For example, the call routing system may automatically identify the phone number from which the call originates and retrieve account information associated with the identified phone number

In step 202, call routing decisions may be made. Based on information collected, decisions may be made to route the call to a proper target (e.g., a qualified agent at a queue at a call site). At the same time and/or following the call decisioning, an assessment of the system resources may be made. The system resources may include, for example, the number of phone lines available for call routing, the number of call site centers and/or qualified agents available to handle the call.

In step 204, it may be determined whether the call routing system is ready to service the call soon. Based on the call routing decisions) and/or resource assessment, it may be estimated as to how long, the caller will have to wait before the call an be properly routed and adequately serviced by a qualified agent. Sometimes, a call routing system can be overloaded with inbound calls and a long queue of callers may already have been kept waiting for service. If that is the case, it may be determined that the system is not ready for prompt service of the call. Therefore, in step 206, the caller may be notified of the situation and offered a number of options to receive a call-back at a later time.

The decision on call-routing and/or call-back options may also be based at least in part on a priority the caller. A caller may have been categorized into different priority classes depending on the caller's identity, account states and business relation, etc. Callers with higher priorities may require more expedited services than those with lower priorities.

The threshold(s) for call routing and call-back options may be flexibly configured and updated by an administrator of the call-routing system. As mentioned above, the threshold(s) may take into account various factors such as length of queue, priorities of the callers, and availability of system resources, for example. The status of the call-routing system may be dynamically monitored and compared to the predetermined thresholds. If one or e of the thresholds are met, the functions associated with call-back options may be triggered.

If the estimated wait is relatively short, the call may be immediately routed to its proper target and queued for service in step 210. While the caller is waiting on line to be serviced, call-back options may still be available in step 212. For example, if somehow the wait is longer than estimated or if the caller somehow has to get off line sooner, the caller may still choose to receive a call-back at a different time. The call-back options may be accessible, for example, by pressing one or more touch-tone buttons.

The call-back options as offered in steps 206 and 212 may be presented to the 20 caller via an interactive voice response unit For example, a voice may announce to the caller,“We can take your information and call you back.” Then a number of call-back options may be presented for the caller to select.

According to one embodiment of the present invention,the system may offer to call the caller back at a first opportunity, i.e. as soon as system resources become available to service this particular caller.

Or the system may oiler be caller at a specific time. For example, the caller may specify a preferred time or time range to receive a call-back. For example, the caller may choose receive a call-back at or around 8 PM, or between 8 PM and 8:30 PM. The caller may also have the option to specify more than one time or time range to receive the call-back. For example, the caller may enter a second or third preferred time or time range to receive the call-back. In the event when the system is not able to call or reach fee caller at the first specified time or time range, a second or third attempt may be made to reach the caller.

Another call-back option may be to call the caller at a relative time or time range with respect o the time of the current call. For example, the caller may choose to receive a call-back in exactly three hours or during the next two hours. Again, a second and third choice may be selected in case the caller cannot be reached at the first specified time or time range.

According to embodiments of the present invention, the above described call-back: options may be combined. For example, a caller at work who is leaving the office in four hours may have the system to call back: as soon as possible during the next four hours or otherwise to call back the next day during work hours when the caller is back in the office. In addition, one or more phone numbers n be provided by the caller to indicate where the caller would like to receive be call-back. Furthermore, different phone numbers may be provided in each of the call-back options and/or their combinations. For example, the caller may have the system call a business phone during the day and a home phone In the evening hours, if no phone number has been specified by the caller for the call-back purpose, the number from which the current call is made (“Caller ID”) may become a default call-back: number. Other variations and/or combinations of call-back options are also available.

In step 208, the caller may select a call-back: option. If the caller does not make a selection or choose to stay on line, the call may be routed and queued for service in step 210. If the caller does choose one of the available call-back options, the caller's selection may be recorded in step 214. The caller's selection ay include the preferred phone number(s) by which the caller an be reached and foe preferred time or time range(s) when the call-back is expected. According to embodiments of the present invention, the caller may also leave one or more voicemail messages to provide additional information associated with foe call and call-back. Further, the caller may visit a designated Internet website to enter the call-back options. For example, the IVR may announce the website address. The caller may choose to hang up and go online to specify the above-described call-back preferences including time, phone number(s) and combinations thereof. The call-back preferences may be communicated to the call-routing system via a network connection.

According to embodiment, the initial phone call, the selection of call-back options, and/or the call-back operation may be carried out over the Internet Voice over IP or VoIP) or may be based on other telephony technologies (e.g., voice recognition). For example, as a caller snakes a VoIP call from a networked computer to a call center, the caller may be able to select a call-back option in a variety of ways. Apart from the touch-tone method, voice recognition technology may be used to record the caller's response or a web dialog window may pop out on the caller's screen for selection of call-back options.

In step 216, resources of the call routing system may be re-allocated based, at least in part on the cad-back options recorded and/or accumulated in die system. During times of high demand, an increasing number of callers may have selected call-back 5 options. In the meantime, as agents continue to process existing calls in the queue(s), system resources may become available. As a result, the system resources, such as the phone lines and qualified agents, may be re-allocated to service new incoming calls and the scheduled call-backs. According to one embodiment of the present invention, a resource re-allocation strategy may be implemented by the call routing system to dynamically assess the demands on the system versus available resources, and allocate the limited resources fox different call-processing tasks. For example, the number of live callers and scheduled call-backs may be considered in determining what portion of the agents may be switched to service call-backs. In addition the call-backs may be prioritized based on a plurality of predetermined criteria. For example, call-backs concerning more urgent or time-sensitive businesses may have higher priorities than the others. The call-backs may also be prioritized based on the priority classes of the callers.

In step 218, the customer may be called based on the call-back option selected.

According to an embodiment of the present invention, the call-back may be initiated by a live agent or an interactive voice response unit. For example, an IVR may dial a number at a certain time, where the number has been specified by the customer and the time is in accordance with the call-back option selected earlier by the customer.

In step 220, it may be-determined if the caller is available to take the call. If no one answers the phone and a voicemail prompt is heard, the IVR moray leave a message for the customer in step 224 and the system may schedule another call-back in a later time.

If the customer answers the phone, the system may proceed with the call-back in step 222. For example, the IVR may greet the customer with a voice saying “Your call is scheduled . . . can you take it now?” The IVR the customer further interactive 5 options such as taking the call now, rescheduling the call or canceling the call. If the customer decides to take the call, the call may be routed to be serviced by a live agent immediately. If the customer decides to reschedule the call, the same or a similar menu of call-back options as described above may be presented to the customer for selection. Based on the customer's response to the call-back and/or the further options, information concerning this customer's call-back options may be updated in the call routing system.

The exemplary method ends in step 226.

According to embodiments of the present invention, the above described method for providing call-back options may be implemented in a number of ways, it may be integrated in a call routing system or operate as an add-on system to an existing call-routing system or call site center system.

FIG. 1 is a block diagram illustrating an exemplary call routing system in which embodiments of the present invention may be implemented. U.S. patent application Ser. No. 10/286,767, entitled “System and Methods for Call Decisioning in a Virtual Call Center Integrating Telephony with Computers,” filed on Nov. 4, 2002, discloses a server-based call routing system, an overview of which is illustrated in FIG. 1. This call routing system comprises central server system 100; data logger system 110; administrative controller system 115; call router database 105; IVR system i 125; IVR system2 120; call site center system! 145; call site center system2 ISO; call site center systems 155; IXC interface 127; inter-exchange carrier (IXC) 130; local exchange carrier 135; web interface 160; and caller 140.

Central server system 100 comprises a server system for centralized control over the call routing and call-back options in the call routing system. Generally, central server system 100 includes hardware and software for supporting system administration, database management, carrier network interface, and transmission/reception of data to/from the central IVR's (blocks 120 and 125) and call site center systems (blocks 145-155). In general, central server system 100 receives routing requests from inter-exchange carrier (IXC) 130, processes said requests as well as other information, and then issues a return route address to IXC 130 to control where a call is routed.

Data logger system 110 comprises hardware and software for logging activity of the call routing system. Administrative controller system 115 may comprise a workstation or the like for administering and monitoring the call routing system. Call router database (CRD) 105 comprises storage means for storing data for the call router system. IVR system1 125 and IVR system2 120 collect Information from callers (e.g., using touch-tone activated voice menus) order to route calls to the proper target, such as to a qualified agent at a queue at a call site.

Call site center systems 1-3 (blocks 145-155) comprise call sites for receiving calls forwarded by IXC 130. Generally, said call sites will comprise one or more so-called peripherals capable of receiving calls, such as local VRU's, PBX's (Private Branch Exchange), and ACD's (Automatic Call Distributors). Said call sites generally include agents and agent workstations for human-assisted call processing.

IXC interface 127 represents hardware/software that may be required to convert data transmitted between IXC 130 avid central server system 100. IXC 130 represents the Song distance carrier network that is controlled by central server system 100 to route calls to call sites and queues at the different geographic locations. Local exchange earner (LXC) 135 represents a local phone network the receives a customer's call in a local area for forwarding to IXC 130.

Web interface 160 may be an interface or connection between an Internet website Sand the central server system 100. User 140 may interact with the website to enter call-back preferences that are subsequently communicated to the central server system 140 and stored in CRD 105.

In this call routing system as depicted in FIG. 1, the method for providing call-back options in accordance wife the present invention may be implemented, both at the system level and at the call site level.

At the system level, all the activities related to call-back options may be controlled and coordinated by central server system 100. For example, when caller 140 calls in, the call may be first forwarded (i.e., pre-routed) to one of the IVR systems (e.g., IVR system1 125). Caller 140 can receive automated servicing and access his/her accounts) using touch-tone controlled menus. If caller 140 seeks servicing by a live agent, a routing request may be sent to central server system 100. Central server system 100 may interact with CRD 105, data logger system 110, administrative controller system 115 and other system resources to make a call-routing decision, Central server system 100 may not only identify a suitable call-routing target (e.g., call site center and/or agent) for the service requested, but also assess the availability of the target. For example, it may be determined how many callers are already queued for the target and how long caller 140 may be kept waiting, if the call site center and/or agent is immediately available to service the call, the call may be routed accordingly. If, however, the call site center and/or agent is not immediately available, central server system 100 may instruct IVR system1 125 to present a plurality of call-options to caller 140. If caller 140 chooses to stay on line, the call may be routed to the suitable target and queued for service. If caller 140 selects one of the call-back options, the caller's call-back preferences and any additional information may be recorded by IVR system1 5 125 and sent to central server system 100, where the call-back information is processed before being sent to CRD 105 for storage.

Central server system 100 may continuously or periodically assess the system resources, re allocate the resources, and schedule call-backs. When it is time for a scheduled call-back, central server system 100 may retrieve the relevant caller information and call-back information from CRD 105 and pass the information on to one of the IVR systems (e.g., IVR system2 120) with instructions to initiate a call-back.

At the call site level, the call-back options may be provided to the callers in a service queue for a call site center or call agent. Much like the operations at the system level, the resources of the call site center may be evaluated against ongoing service requests. The resources may be dynamically re-allocated between the service for live callers and the service for call-backs.

As noted earlier, the call:back options may be implemented in an add-on system to an existing call-routing system or call site center system. FIG. 3 is a block diagram illustrating an exemplary system 300 for providing call-back options according to an embodiment of the present invention. System 300 comprises an Interface 302, a Control Module 304, a Voice Response Unit (VRU) 306, a Storage Module 308, and a Web Interface 310. I/O Interface 302 may function as an data/voice interface between System 300 and an exist call-routing system or call site center system. For example, connections may be made through I/O Interface 302 for telephone voice streams as well as computer data streams. Control Module 304 may be a processor capable of data manipulation, logic operation and mathematical calculation. It can also interact with the other components in System 300 and coordinate their operations. VRU 306 may have interactive means (e.g., touch-activated voice menus) to communicate with callers and collect information from them. Storage Module 308 may comprise storage means (e.g., semiconductor memory, h ad disk, nonvolatile memory and CD-ROM etc.) for storing call-back related information such as caller data and call-back preferences. Web Interface 310 may comprise an internet website where a caller or visitor may interactively enter call-back options.

In operation, System 300 may interact with the existing call system to provide call-back options. System 300 may either be a passive subordinate to the existing system or it may actively supplement the existing system with call-back functions. In a passive role, System 300 may simply receive calls routed from the existing system. For example, if a caller's queue in the existing system reaches a predetermined length, additional calls may be automatically routed to System 300. In an active role, System 300 may evaluate system load of the existing system, identify the callers who might need call-back options, and re-route those calls. Control Module 304 may receive caller data as well as other information or instructions from the existing system via I/O Interface 302. Accordingly Control Module 304 may give instructions to VRU 306 to greet the caller, offer the call-back options and record she caller's selection. Alternatively, the caller may be directed to visit an internet website associated with Web Interface 310 to enter call-back options. The call-back related information may then be processed in Control Module 304, where the call-backs may be prioritized and scheduled. The processed data may be stored in Storage Module 308, Control Module 304 may receive status reports from the existing system and use the status data in processing the call-backs. When it is time for a scheduled call-back, Control Module 304 may rein eve the relevant data from Storage Module 308, instruct VRU 306 to Initiate a call to the customer, and coordinate with the existing system to route the call to a proper target.

At this point, it should be noted that the system and method for providing call-back options In accordance with the present invention are not limited to inbound calls into a call-routing system, in fact, call-back options may be provided to any person who attempts to communicate with a business or individual. The communication may be via mail, telephone, internet or in person, for example. If such is the case, it is within the scope of this invention.

While the foregoing description includes details and specificities, it is to be understood that these have been included for purposes of explanation only, and are not to be interpreted as limitations of the present invention. It will be apparent to those skilled in the art that other modifications to the embodiments described above can be trade without departing from the spirit and scope of the invention. Accordingly, such modifications are considered within the scope of the invention as intended to be encompassed by the following claim and their legal equivalents.
